Job Title: Senior DevOps Engineer

Location: Sofia

Overview of the Role

Each tribe consists of squads (typically 58 engineers) responsible for delivering features services and platform capabilities within their technical domain.

As a DevOps Engineer you will design automate and maintain the infrastructure CI/CD cloud orchestration and deployment tooling that drive reliability scalability and engineering velocity. You will collaborate closely with software engineers QA architects and product teams to ensure secure predictable and efficient delivery across environments.

You will be hands-onbuilding infrastructure with Terraform deploying workloads via Helm charts managing Kubernetes/EKS/ECS clusters optimizing pipelines and improving overall engineering systems.

What Youll Do

Engineering Automation & System Ownership

• Design maintain and optimize CI/CD pipelines using GitHub Actions Jenkins and other automation tools.

• Build and manage cloud infrastructure using Terraform (IaC for AWS VPC ECR networking IAM policies autoscaling).

• Deploy and maintain containerized applications using:

  • Kubernetes

  • AWS EKS/ECS

  • Helm charts for packaging versioning and rolling out workloads

• Implement and evolve Kubernetes standards for namespaces ingress RBAC resource limits autoscaling (HPA/VPA) and monitoring.

• Optimize container build pipelines (Docker multi-stage builds security scanning caching).

• Collaborate with developers to enhance build systems testing frameworks and optimized deployment workflows.

• Use GitHub and Git-based workflows (branching PR policies automation triggers) to ensure code and pipeline quality.

• Troubleshoot issues across infrastructure pipelines deployments clusters and cloud environments.

• Participate in on-call rotations for production support and incident response.

• Ensure compliance with security audit and regulatory standards in infrastructure and deployments.

Foster a Sustainable & Scalable Engineering Culture

• Contribute directly through coding scripting automation Terraform modules Helm chart creation cluster configuration and performance tuning.

• Work with tools and technologies including:
  GitHub GitHub Actions Helm Terraform Kubernetes AWS EKS AWS ECS Jenkins BitBucket Grafana Prometheus Logstash CloudWatch Nginx Kafka Ubuntu
  and languages such as Java JavaScript NodeJS PHP Go Groovy

• Promote DevOps best practices:

  • Infrastructure as Code (Terraform)

  • Kubernetes management

  • Reusable Helm charts and pipelines

  • Zero-downtime deployments

  • Automated rollbacks and progressive delivery

• Drive adoption of technical enablers such as:

  • GitHub Actions workflows

  • Protected branches PR approvals automated checks

  • Terraform modules & pipelines

  • Helm chart repositories and versioning

  • EKS/ECS deployment automation

  • Static analysis & security scanning

  • Monitoring logging & alerting using Grafana CloudWatch Prometheus OpenTelemetry

• Contribute to engineering documentation playbooks standards and knowledge sharing.

• Support backlog refinement to balance feature work with infrastructure and operational improvements.

Champion Quality & Continuous Improvement

• Participate in planning estimation and prioritization of DevOps and cloud infrastructure tasks.

• Build resilient secure scalable infrastructure using Terraform Helm and Kubernetes best practices.

• Improve deployment reliability scalability and performance across EKS/ECS clusters.

• Lead diagnostics incident resolution root cause analysis and remediation follow-up.

• Collaborate with QA Architecture Product and Software Engineering to ensure system quality.

• Ensure the Definition of Done includes documentation tests observability IaC updates and deployment validation.

• Promote experimentation innovation automation and internal knowledge-sharing initiatives.

Stakeholder Collaboration & Communication

• Act as a key technical partner for engineering QA architecture and product teams.

• Communicate infrastructure changes risks and dependencies clearly and transparently.

• Participate in design reviews and architecture discussions especially regarding cloud Kubernetes and deployment approaches.

• Ensure DevOps practices align with business architectural and platform objectives.
